10-Gigabit X2 Transceivers
10GBASE-DWDM X2 Transceivers
The Dense Wavelength Division Multiplexing (DWDM) X2 transceivers are part of a DWDM optical
network to provide high-capacity bandwidth across a fiber-optic network. There are 32 fixed-wavelength
DWDM X2 transceivers that support the International Telecommunications Union (ITU) 100-GHz
wavelength grid. These transceivers have duplex SC connectors. DWDM X2 transceivers can transmit
and receive optical signals up to 50 miles (80 km) depending on the quality of the fiber-optic cable used.
DWDM X2 transceivers look like the typical 10GBASE-X X2 transceivers as shown in Figure B-2 on
page B-5.
For the specifications that differentiate the 10GBASE-DWDM X2 transceivers, see Table B-8.
